TRIPOLI, May 2 (Xinhua) -- A total of 392 people have been killed and 1,936 others injured in the fighting between the UN-backed Libyan government and the east-based army in and around the capital Tripoli, the World Health Organization (WHO) said Thursday.

In addition, some 50,000 people are estimated to be displaced, said WHO via Twitter.

The east-based army, led by Khalifa Haftar, has been leading a military campaign since early April to take over Tripoli, where the UN-backed government is based.

During a cabinet meeting earlier Thursday, Libyan Prime Minister Fayez Serraj said there will be no cease-fire until the rival army forces "return to where they came from."

Libya has been struggling to make a democratic transition amid chaos since the fall of former leader Muammar Gaddafi in 2011.
